Answer:
y = -3/8x + 31/8
Step-by-step explanation:
y=-8/3x slope: -3/8
parallel: (y-5) / (x-(-3))= -3/8
-3*(x+3)=8*(y-5)
-3x-9=8y-40
8y = -3x +31
y = -3/8x + 31/8

Since 2005, the amount of money spent at restaurants in a certain country has increased at a rate of 5% each year. In 2005, about $290 billion was spent at restaurants. If the trend continues, about how much will be spent at restaurants in 2020? PLEASE HELP ME
Answer:
About $603
Step-by-step explanation:
Given data
The time interval 2005-2020= 15 years
The principal amount spent= $290 billion
The rate= 5%
Let us apply the compound interest formula
A=P(1+r)^t
substitute
A=290(1+0.05)^15
A= 290(1.05)^15
A= 290*2.0789
A= $602.881
Hence about $603 will be spent in 2020
Model With Mathematics A photographer is
placing photos in a mat for a gallery show.
Each mat she uses is x in, wide on each side.
The total area of each photo and mat is
shown
Answer:
a. The possible dimensions of the total area are;
The width of the total area is (2·x + 8) inches
The length of the total area is (2·x + 10) inches
b. The dimensions of the photos are as follows;
The length of the photos are 10 inches
The width of the photos are 8 inches
Step-by-step explanation:
a. Given that the area, A = 4·x² + 36·x + 80
We get;
A = 4 × (x² + 9·x + 20) = 4 × (x + 4) × (x + 5) = (2·x + 8)·(2·x + 10)
Therefore, the possible dimensions of the total area (photo + mat) are;
The width of the total area (photo + mat) = (2·x + 8) in.
The length of the total area (photo + mat) = (2·x + 10) in.
b. The dimensions of the photos alone are shorter than the dimensions of the photo and mat combined by 2·x each
Therefore, we have the dimensions of the photos are as follows;
The length of the photo = (2·x + 10) in. - 2·x in. = 10 in.
The width of the photos = (2·x + 8) in. - 2·x in. = 8 in.

What is 2x+5=25? I would like to know it step by step please.
Step-by-step explanation:
subtract 5 from 25 and it should look like this
2x=20
divide 2 and your is 10
Answer:
No problem! Well first off, x is 10.
Step-by-step explanation:
So you know that 2 times a certain number, plus 5, is 25. The first step to solving this problem is subtracting 5 from the total (25) to give you 20. This just makes it easier to find x, so you technically don't have to do it. So now, you know that 2 times a certain number equals 20 (because we got rid of the 5). Now, just divide your number (20) by 2, to get that x is 10. Let's check our answer.
2(10) + 5= 2520 + 5= 25
25= 25.
Works out!

-3y > -14
Answer:
y < 14/3
Step-by-step explanation:
You can immediately negate the negative from both sides by canceling the -1.
Divide both sides by 3, when you divide a < or > by anything you have to switch the sign it faces. So in this case
-3y > -14
=> 3y < 14
y < 14/3

If the black square rotates at a rate of 2 inches per second, how long would it take for one full rotation?
Answer:
The answer is below
Step-by-step explanation:
The question is not complete.
Let us assume that the black square rotates in a circular part of radius 1 inch.
Therefore, in one full rotation the distance covered (θ) is the same as the perimeter of the circular part. Therefore:
θ = 2πr = 2π(1) = 6.28 inch
The time taken to complete one full rotation (t) is:
t = θ / v
t = 6.28 / 2
t = 3.14 seconds
can yall help thank you in advance
Answer:
Step-by-step explanation:
Perimeter of the deck = (d + 5) + (d + 5) + (d + 5) + (d + 5)
1). By grouping method,
Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)
2). Perimeter = Number of sides × Length of a side
= 4(d + 5)
3). Expression from problem 1,
Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)
= 4d + 20
= 4(d + 5)
Expression from problem 2,
Perimeter = 4(d + 5)
Bot the expressions are same.
Jennifer deposits $1,000 into an account that is compounded monthly for 4 years. The account earns 7% interest. What is the ending balance in the account at the end of the 4 years (assuming no new deposits or withdrawals)? SHOW THE WORK PLEASE
9514 1404 393
Answer:
$1,322.05
Step-by-step explanation:
The compound interest formula is appropriate.
A = P(1 +r/n)^(nt) . . . principal P earning annual rate r for t years, compounded n times per year
You have P=1000, r=.07, n=12, t=4, so the balance is ...
A = $1000(1+.07/12)^(12·4) ≈ $1000(1.322054)
A = $1,322.05
Jennifer's ending balance is $1,322.05.

Answer:
distance = 10.6
Step-by-step explanation:
A's coords are (5, 6)
D's coords are (-2, -2)
So the total horizontal distance between A and D is:
5 + 2 = 7
...and the total vertical distance is:
6 + 2 = 8
Now use Pythagorean Theorem:
7^2 + 8^2 = distance^2
distance^2 = 49 + 64 = 113
distance = squareroot of 113
distance = 10.6

Peter needs to build a fence around his small garden. The length of the fence can be no more than 10 ft., and he has 50 ft. of fencing that he can use. What are the possible dimensions of his garden?
Answer:
A backyard farmer wants to enclose a rectangular space for a new garden. She has purchased 80 feet of wire fencing to enclose 3 sides, and will put the 4th side against the backyard fence. Find a formula for the area enclosed by the fence if the sides of fencing perpendicular to the existing fence have length
L.
In a scenario like this involving geometry, it is often helpful to draw a picture. It might also be helpful to introduce a temporary variable,
W, to represent the side of fencing parallel to the 4th side or backyard fence.
Since we know we only have 80 feet of fence available, we know that
L + W + L = 80, or more simply, 2L + W = 80. This allows us to represent the width, W, in terms of L: W = 80 – 2L
Now we are ready to write an equation for the area the fence encloses. We know the area of a rectangle is length multiplied by width, so
A = LW = L(80 – 2L)
A(L) = 80L – 2L2
This formula represents the area of the fence in terms of the variable length
L.
Step-by-step explanation:
it's in the answer
